The Kybalion is a book written by three unidentified authors who claim to have studied the ancient hermetic teachings. The main message of the book is that there are three universal laws governing all of reality. These laws are called "the principles of mentalism," "the principle of vibration," and "the principle of polarity." The Kybalion teaches that by understanding these principles, we can learn to control our thoughts and emotions, and create our own reality. Read in English, unabridged.
